Madshus World Cup Biathlon Pole Straps.  Favored by top racers like Ole Einar Bjoerndalen and Emil Hegle Svendsen.  Wide strap loop for effective power transfer while maintaining ease of use for fast range times.  Padded strap with non-skid material helps to keep the strap comfortably in place while poling.  Will work on most 'standard' ski poles with friction adjustment plugs in the top of the grips.  Made in China.
